A Philippines mining company required a reliable iron ore beneficiation solution to improve the quality of locally mined hematite ore. Based on the ore characteristics and processing requirements, Baichy Machinery provided key beneficiation equipment, including a 3200×4500 ball mill and spiral classifier, to support the customer's hematite processing plant.
The customer adopted a gravity separation process for hematite beneficiation. By utilizing the density difference between iron minerals and gangue minerals, the process can effectively upgrade iron ore concentrate while reducing waste materials.

The hematite beneficiation process is mainly determined by the ore particle size, mineral composition, and degree of mineral liberation. According to different ore characteristics, hematite gravity separation can be divided into coarse particle separation and fine particle separation.
1. Crushing and Grinding Process
The raw hematite ore first enters the crushing stage to reduce the particle size and prepare suitable feed material for grinding. For finely disseminated hematite, grinding is an important step to achieve mineral liberation. The ore enters the ball mill 3200×4500 supplied by Baichy Machinery, where the iron minerals are fully separated from gangue minerals through efficient grinding. After grinding, the slurry enters the spiral classifier for particle size classification. Qualified fine particles are sent to the beneficiation stage, while coarse particles return to the mill for further grinding, forming a closed-circuit grinding system.
2. Gravity Separation Process
After classification, the suitable slurry enters the gravity separation stage. Gravity separation mainly uses the density difference between hematite and waste rock minerals. Heavy iron-bearing minerals settle faster, while lighter gangue minerals are separated and discharged as tailings. For coarse-grained hematite ore with relatively high geological grade, the "crushing without grinding" process can be adopted. Coarse tailings can be removed directly through gravity separation, reducing grinding energy consumption. For fine-grained hematite ore, grinding and gravity separation are combined to achieve better mineral liberation and improve iron concentrate grade.
3. Magnetic Separation and Gravity Separation Combination
For some weakly magnetic iron ores, gravity separation alone may not achieve the required concentrate grade. Therefore, a combined magnetic separation + gravity separation process is often used. The process usually adopts:
● Weak magnetic separation to remove strongly magnetic minerals such as magnetite;
● Strong magnetic separation to discard low-grade tailings;
● Gravity separation to further upgrade magnetic concentrate.
This combined process improves beneficiation efficiency and produces higher-grade iron concentrate.



According to the project requirements, Baichy provided key equipment for the hematite beneficiation plant, including:
1. Ball Mill 3200×4500
The large-scale ball mill is used for grinding crushed iron ore. It provides sufficient grinding force to achieve mineral liberation and improves the efficiency of downstream beneficiation.
2. Spiral Classifier
The spiral classifier is used for slurry classification. It controls grinding fineness, separates qualified materials, and improves the stability of the entire beneficiation process.
3. Other Supporting Equipment
A complete iron ore beneficiation plant may also include:
● Crushing equipment
● Feeding equipment
● Belt conveyors
● Magnetic separators
● Gravity separation equipment
● Concentrate and tailings handling systems
The final equipment configuration is customized according to ore properties and production capacity.
1. Customized Process Design
Different hematite ores have different mineral characteristics. Baichy designs beneficiation solutions according to actual ore conditions, including grinding fineness, separation method, and equipment selection.
2. High Resource Utilization Efficiency
The combination of efficient grinding and gravity separation improves mineral liberation and reduces the loss of valuable iron minerals in tailings.
3. Energy-Saving and Cost-Effective Operation
For suitable hematite ores, gravity separation can reduce the use of chemical reagents and lower operating costs. The optimized process design helps customers achieve stable production with reasonable investment.
